FIG= i WITNESSES iso WILLIAM J. PANNIER, an, or PITTSBURGH,rENnsYLvAnIA, ASSIGNOR To-rnnmnn. BROS. STAMP comrm, or PITTSBURGH,PENNSYLVANIA, A conroan rron or PENNSYLVANIA.

The invention has in view to provide, in.

a stamp in which the units are removably inserted, as in dating stampsor the like, a

holding base for the units having a recessed dove-tail or wedge-shapedcavity, and units having correspondingly shaped insertible' bases, sodesigned as to provide for contraction of the base to facilitateinsertion and removal, and suflicient expanding action within thewedge-shaped socket to insure holding retention therein during normaloperation.

One embodiment of the invention, in its simpler form, is illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view of ahand stamp embodying my invention. Fig. 2 is a cross sectional Viewtaken on the line H. II. of Fig. 1. Fig. 3 is a similar view, showingthe operation of inserting or removing .one of the units. Fig. 4 is aperspective detail view of one of the units, removed.

While the invention is articularly adapted for hand stamps, utilizing.rubber units or inserts, it will be readily understood that it isapplicable to any of the various wellknown constructions of stamping orprinting devices utilizing removable rubber inserts and a suitablesupporting base.

In the drawings, the main base 2, which may be of metal, wood, or othersuitable material, is provided'with a holding handle 3, or any othersuitable actuating means. The base 2 is provided with a receiving cavity4 for the stamping units or inserts 5 having on their operative facesletters or figures or other suitable devices, adapted to be inked andstamped upon any surface.

The inserts 5 are preferably made of rubber or other suitable materialhaving the desired resiliency for the printing letters, figures, etc.,and acting as a cushion inthe usual way, and also providing, in theattaching base portion of the insert, for exv STAMP.

Application filed November 11, 1915. Serial No. 60,861. Y

,,The middle portion of the unit or insert base is cut away or hollowedout, as at 8, whereby to provide the two diverging base members 9, 9.The inner walls of the cavity 8 substantially conform as to theirinclination to the outer walls 7, and the base members 9 are thus easilycompressed together, as in Fig. 3,so as to render their outer facestemporarily substantially straight and parallel from top to bottom,thereby facilitating either insertion or removal of the insert. I

When inserted, as in Fig. 2, the base mem-- bers 9 will spring outwardlyagainst the sloping walls 6, practically filling the cavity, and firmlyretaining the insert in position during ordinary use.

As will be observed, the inner contacting bottom faces of the basemembers 9 are preferably flat across their width, providing asubstantially flat confronting hearing, so that the insert ispractically solid from bottom to top, and the rubber is-in a con--dition of normal expanded shape'within the cavity. I thus provide,within the base, a

' firm holding engagement between the base and the insert, and beyondthe face of the base and the inserted root portion of the insert, theextended ortion of the unit having the desirable resilience andcompressibility,

combined in a. single holding base with permanently attached printingunits, dependingnpon the entire stamping capacity of the devlce.

The invention 'may be variously changed in other respectsas to detailconstruction, design, or other features, depending upon the requirementsof thevmakeror user, but all such changes are to be considered as withinthe scope of the appended claims. What I claim is;

1. A stamplng device comprising a hold ,panding resiliency within thesocket 4.

ing base having an inwardly enlarged wedge-shaped socket, and aresilient printi'ng unit having "a correspondingly shaped base formed oftwo normally separated resilient parts inserted therein. 7

2. A stamping device comprising a holding base having an undercutinwardly flaring socket, and a resilient printing unit having acorrespondingly shaped base formed of two normally separated resilientparts inserted therein. a

, 3. A stamping dei'ice comprising a holding base having an inwardlyenlarged socket, and a resilient printing unit having a base formed oftwo normally separated divergent parts adapted to be ressed together andinserted therein, an to re-act intp holding engagement with the socketwa ls.

4. A stamping device comprising a holding base having an inwardlyenlarged socket, and a printing unit having a correspondingly shapedbase formed of two normally separated compressible resilient partsinserted therein.

5. A stamping device comprising aholding base having a socket providedwith in wardly diverging walls, and a printing unit having a projectingstamping portion and an integral base formed of two normally separatedresilient holding parts 'divergin from the stamping portion and insertetherein. g

6. Astamping device comprising a holdto bring their outer faces into theplanes of the sides of the stamping portion and to resiliently react tonormal position.

8. A-rubber printing unit of the class described having an integral baseformed of two normally separated parts having diverging outer and innerfaces providing an intervening ll-sha-ped space and adapted to becompressed together for insertion into a correspondingly shapedreceiving socket andnto resiliently re-act "to normal position.

9. A rubber printing unit of the class described having aprojecting-stamping portion and an integral base formed of two normallyseparated parts diverging anguing portion.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
